• Degrees to Ratio and Percentage

  Convert the angle of a slope — a ramp, for example — from degrees to a rise:run ratio and a percentage gradient.

• Degrees Celsius to Watts per Square Metre

  Convert a temperature in degrees Celsius to the equivalent black-body radiant heat flux in watts per square metre.

• Grid to Radius

  Convert the spacing of a detector or sprinkler grid into the radial distance from a fire at the centre of that grid — the worst-case travel distance to the nearest head.

• Percentage to Degrees and Ratio

  Convert the gradient of a slope — a ramp, for example — from a percentage to an angle in degrees and a rise:run ratio.

• Radius to Grid

  Convert the radial coverage of a detector or sprinkler head into the maximum square grid spacing that keeps a fire at the centre within that radius.

• Ratio to Degrees and Percentage

  Convert the rise and run of a slope — a ramp, for example — to an angle in degrees and a percentage gradient.

• Watts per Square Metre to Degrees Celsius

  Convert a radiant heat flux in watts per square metre to the equivalent black-body temperature in degrees Celsius.
